This duffel holds an amazing amount of gear and, is big enough to carry you all the way through an expedition of 2-4 weeks. It’s the same bag that explorer Will Steger used on his Trans-Antarctic Expedition in 1990, the first non-mechanized crossing of the Antarctic. He still uses the same duffel today. This is the same duffel as the #5 SP but, without the outside side pockets to cut weight and, price. With rugged construction and 25 years of field-tested design features, this duffel is ready to take you on your next big adventure.
